Letters Patent No. 62,819, lated Februizrj/ 26, 1867.

IMPROVED VISE.

TO ALL WHOM IT MAY GONCERN:

Be it known that I PE'LER. CROWL, of Brownsville, in the county ofFayette, and State of lennsylvania, havel invented a new usefulImprovement in the Construction of y Vises; and I do hereby declare'that the following is a full, clear, and exact description of thesaine, reference being'had' to the annexed drawings, making part of thisspecification, in whichw Figure l is a perspective view and Figure 2 isa vertical longitudinal section.

The same letters are employed in both figures in the indication ofidentical parts.

These improvements nre made in the vise patented by myself` on the 29thof May, A. D. 1866, towhich -I make reference.

A represents the bench to which the vise is attached. Bis apla-te boltedto the bench; the'cover C is bolted thereto, the stationary C being Iapart thereof. D is the movable jaw, attached by a swivel stemto thesliding stock D which passes through a chamber formed between the plateB, (which is formed to receive it,) and the cover C. The stock hasratchet teeth out in its lower face, as shown. E is a lever pivoted upona pin passing through lugs depending from the plate B, from which saidlugs also is suspended the swinging stirrug E2, which holds the end ofthe spring El, by the tension of which the end of the lever E is pressedupwards the rear ehd of the lever cut away to half its thickness toreceivea similarly constructed end of the 'pawl F, attached by a pivoton which it turns freely, being pressed upward and sustained with itspoint pressing against the rack upon the stock D by the spring F; Whenthe long end of the lever E is drawn down, the short end presses thepoint of the pawl F forward, which, catching upon the rack under thestock, draws the jawD towards the jaw C. When the long end of the leveris raised, the pawl is drawn back, sliding over the inclined faces ofrack. Thus by the action of the lever the jaw D is closed upon thejaw C.This motion of the leverE is effected by the foot-lover H, (a lever lofthe third order,) pivoted at the inner end to the bench, and connectedby the rod G with the long end of the lever E.' The notched 'plate Hholds the lever H in position, retaining the grip of the vise. Theadjustahle'jaw D conforms to the face of the object enclosed. This jawmay be pressed by.

hand against the object, the pawl slipping over the teeth in the rack onD', and there it is compressed and retained by pressing down the leverH.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the stationary jaw C, adjustable jaw D, and stock D',pawl F, and lever E, and springs F and El', all of said parts beingrespectively constructed and arranged for use substantially in themanner and for the purpose set Forth.

In testimony whereo` I have signedmy name te'this specification in thepresence of two subscribing witnesses.
